ATTACHMENT FOR SCREENS.

Specification of Letters Patent.

Application filed October 1, 1915. Serial No. 53,603.

To all whom it may concern:

Be it known that S'rERRE'r'r E. MCNULTY, a citizen of the United States, residing at Washington, in the District of Columbia, has invented. certain new and useful Improvements in Attachments for Screens, of which the following is a specification.

This invention relates to improvements in.

window screens and itsleading object is to provide a wmdow screen with means for closing the gap between the screen and the window sash, so that insects will be prevented from entering the window.

Another object of the invention is the provision ofa window screen with means for supporting a gap closing flexible strip, which can be attached to any window screen. A still further object of the invention is the provision of a protecting device for use in connection with window screens, which embraces companion holding frames, each frame being provided with means for connection with one of the sections of an extensionable window screen, and being adapt ed to support on said screen section a flexible strip, whereby the space between the screen and the window sash may be closed, regardless of the adjustment of the screen sections on each other.

With the above and other objects in view the invention consists in certain new and useful constructions, arrangements and C01 1- binatlons of parts, clearly descrlbed 1n the accompanying specification and fullv illustrated in the accompanying drawings, in

. which Figure 1 is a front elevation of an extensionable screen provlded with mylmproved device.

Fig. 2 is a vertical sectional view, on an enlarged scale.

Fig. 8 1s a vertical sect1onal view showing a modified form of screen construction.

tween the folds of the rear pendant flange 6 the screen material A is clamped, in a manner well known in the art.

The inner section 5 is provided with an upper bar 5, which consists of a strip of sheet metal folded on itself, and which is formed with a table flange 5 and a rear pendant flange 5, between the folds of which the screen material B is clamped, as will bereadily understood.

On the table flange 6 of the outer screen frame section 6 the bracketmembers 7 are fixed by means of rivets or screws 8. Each bracket member 7 is provided with an arm 7 adapted to rest on the table flange 6 with a pendant portion 7 adapted to bear against the front pendant flange 6, and a hanger arm 7, which projects horizontally away from the front pendant flange 6.

To the brackets 7 of the section 6 the hold ing frame bars 9 and 10 are secured by the screws or rivets 11, and between said frame bars 9 and 10 the flexible strip 12 is clamped, said strip-projecting laterally of the holding bars 9 andlO, so as to lie partly under the table flanges and partly outside of the pendant flange 6.

To the rear pendant flange 5 of the frame section 5, the brackets 13 are secured by the rivets or screws 14'. Each bracket 5 13 i provided with a vertical arm 13 Patented July 1'7, 1917. p

adapted to contact with the pendant flange 5. and is also provided with a horizontal hanger arm 13*,which is designed to lie under the horizontal hanger arm 7 of the bracket To the terminal portions of the hanger arms 13 of the brackets 13 the holding bars 15 and 16 are securedby the rivets or screws 17, and between said bars 15 and 16 the flexible strip 18 is clamped. The flexible strips 12 and 18 are considerably wider than the bars 15 and 16, so as to project laterally thereof and on the opposite sides of the bars 15 and 16.

The flexible strip 18 is designed to lie partly under the flexible strip 12 and in close relation thereto, so as to leave but a small spacebetween the strips, and to permit of the free sliding of the screen frames 5 and 6 on each other.

In Fig. 3 I show a modified form of the invention, consisting of an upper screen frame bar 20, which is made of sheet metal folded on itself and which is provided with the rear pendant flange 20% the table flange 5Q, the from pendant flange {wastrel the lat new erally projecting hanger flange which is designed to take the place of the holding bar 9 and the brackets 7. Againstthe lower side of the hanger flange 20 the flexible strip 21 is secured by the bar 22 and the rivetsor screws 22 The screen frame bar 23 which 'coep'erates with the bar 20, is formed with the usual rear pendant flange 23 and the table flange 23 The bracket members 24 are secured by their rear vertical arms 24:- betw'een the opposing folds of the rear pendant flange, and project horizontally forward under the hanger plate or flange 20 To the bracket members 24 the holding bars 25 are secured by the rivets or screws 26, and between the bars 25 the flexible strip -27 is clamped. The bracket members 24 are secured to the flange 23 by means of rivets-28. I

Having describedrniy invention I claim and desire to secure by Letters Patent 1. A screen frame provided with brackets projecting laterally thereof and providing hanger arms, holding bars secured to the hanger arms, and a flexible strip secured between the holding bars and projecting laterally of the holding bars.

2. combination, companion screen frames, each frame being slidable on the other frame, each frame being provided with a top bar, brackets secured to, the top bar of one of the screen frame top bars, said brackets having pendant portions provided with horizontal hanger arms, a holding bar secured to said hanger arms, a flexible strip secured to said holding bar and projecting laterally thereof, brackets secured to the top bar of the other screen frame and provided with horizontal hanger arms, a holding bar secured to the second hanger arms, and a flexible strip secured to the second holding ba 7 3, A screen frame having a horizontal flange on the top portion thereof and a flexible strip secured to said flange and projecting horizontally under said flange toward the screen and outwardly thereof.

4. A screen comprising frame members slidable on each other, each frame member being provided with a horizontal flange on its upper end, a flexible strip secured to one of said flanges and projecting in opposite directions, and a flexible strip secured to the other frame member and disposed under the first flexible strip and movable with said other frame member.

5. A screen consisting of companion sections united to each other for extensionable action, a flexible strip secured to one of said sections and having freely yielding longitudinal side edges, and a flexible strip secured to the other section and arranged to slide under the first flexible strip and having freely yielding longitudinal side edges.

6. A screen frame having a laterally projecting element on its upper portion and a flexible strip supported on the said element and projecting toward the screen material one way and projecting in an opposite di rection to contact with the panes of a window sash, the longitudinal side edges of said strip being freely yieldable.

7. An extension screen consisting of companion screen frames slidably secured to each other, a flexible strip for each frame, a metallic member secured to each strip and narrower than the strip to which it is secured, said members being 'slidably secured to each other, and means for holding the members and strips on the screen frames, whereby said members and strips will be extended on each other when the screen frames are extended on each other, said holding means supporting the strips so that their outer edge portions will engage the pane of the window sash in which the screen frames are positioned.

In testimony whereof I aflix my signature.
